Explanation

The OPA4392PWR operational amplifier features ultra-low offset voltage, temperature drift and input bias current, enabling rail-to-rail input and output. In addition to the precise DC accuracy, the AC performance has been optimized to achieve low noise and fast stable transient response. Thanks to these features, the OPA4392PWR is an ideal choice for driving high-precision analog-to-digital converters (ADCs) or buffering the output of high-resolution digital-to-analog converters (Dacs).

The OPA4392PWR adopts TI's e-trim™ operational amplifier technology, achieving ultra-low offset voltage and offset voltage temperature drift without any input chopping or automatic zeroing technology. This technology can achieve ultra-low input bias current for current-to-voltage measurement of sensor input or photodiodes, thereby creating high-performance translance-level for optical modules or medical instruments.
